This invention relates to a window ventilator, and has for several of its objects the provision of an improved ventilator that is easilyand quickly installed in an ordinary window opening without defacing the window frame or sash, and which ventilator may be quickly removed from such opening, and when in operative position in the opening is more ecient for regulating the ventilation than heretofore.

Another object is the provision of a window ventilator for use in a window opening that will freely admit airto the room having said opening free from rain, snow, sleet, etc.; even though accompanied by a strong, gusty and changeable wind, and which ventilator is provided with means for regulating the volume of air admitted there through and for controlling the point of said admisson to that portion Where there is no likelihood of rain, snow or sleet entering the room under even the most abnormal and unusual conditions.

Other objects and advantages will appear in the drawing and description, and some of these,`

while apparently of minor significance, are quite important, such as means of insuring a rattleproof installation and one in which the parts that are adjustable will remain fixed in adjusted position automatically. Economy of manufacture and simplicity are further features, together with provision for admitting air while shutting out insects and considerable quantities of dirt.

In the drawing:` y

Fig. 1 is a perspective view of a ventilator illustrative of the invention in which a portion is broken away and in section toshow certain struc-Y ture. Part of the Window frame and sash are also indicated, these elements being conventional.

Fig. 2 is a vertical sectional view taken transversely through a ventilator such as is shown in Fig. 1 except that the closure for the ventilator opening is positioned in Fig. 2 for shutting out more air than the closure in Fig. 1. In dot-dash securely holding the. ventilator in the windowI opening.

In detail, the main body of'theventilator is preferably of rigid, self-sustaining material fabricated to produce an awning-'like shape in which there is a horizontally elongated 'at transversely slanted top I and a triangular end plate 2 at each opposite end. The'edges of each endplate illustrated in the drawing follow vthe contour of a right angle triangle with the edge that corresponds to the hypotenuse being against the top I at an angle of about 45 relative to horizontal, while one of the other edges is vertical and the v third is horizontal.

On each end plate 2 is a pair of spacedparallel vertical strips 3 corresponding'in their spacing to that which is between strips 5 that slidably retain sash 6 therebetween atopposite vertical edges of the latter, while along the upperedge of top I is a horizontal 'upwardly projecting'stripl secured to said top.

The space between each pair of-vertioal strips 3 is adapted to'slidably support a verticallyelongated wedge member 8 `(Fig. 5) therein, while a similar wedge member 9 is adapted to be" positioned within; the spacebetween strips 5 (Fig. 3). When the inclined sides of each pair of wedge members 8, 9 Aare together their oppositely-outwardly facing sides that respectively engage the ventilator and'the 'Window' frame are parallel. The thicker end of* each wedge 8 may partially extend into the space between the strips 3 at each end ofthe ventilator, while the thickerend of each wedge 9 may extend into4 the space between the pairs of strips 5 respeotively,said pairs of wedge members being insertable'into said spaces from above the' ventilator when the lowersash is raised vto its maximum height; Thus the Wedge members 8, 9 at each end :of the ventilator 'will hold the latter tightly inposition in the window opening andwill'also close oi any cracks'that might" exist between theendsfof the ventilator and the sides of the window frame. "If desired, the adjacent sides of each pair of wedge members 8, 9 vmay be'o'f tongue and'groove contour (Fig. 5) soas to insure a tight seal at their adjacent sides. In'each 'of the' end plates 2 and' between the members 13 a`vertically elongated slot I0 through which'the end'of any suitable instrument, such as a screw driver,` pick, or the like, may be inserted'for engagement with a plate II (Fig. `5)' onv m'ember 9 for lifting said member to remove it, 'so that the two members 8, 9 at each end ofthe ventilator may be removed' for removal of the ventilator. Plate II may be serrated on its face that is over opening III to facilitate engagement with such lifting instrument, and each plate 4II ma'y beef metal, 'secured in'member 9 with itsc-outerside vflush with the outer side of said member.. 'Thewedge' members "8, 3 maybe of wood treated to be water repellent, or they `may be of any other suitable material." The. wedge :membersralso function to hold the ventilator in the window opening in such aposition that the lower' sash f1' will-engage the' top I adjacent-strip# and inbverlapping relationA to the latter, thereby preventing ingress of moisture t`o the room over the upper edge of top; I .t

kInside tn ebody "ofthe ventilator and spaced above the lower edge of top I and the lower sides of end plates 2 is a horizontally disposed, centrally open rectangular frame.

This frame may comprise a pair of frames I5, I6 (Fig. 2); with frame-l5 postionedoverframe iii' and with the inwardly facing edges oiL frame I5' projecting slightly inwardly relative; to the corresponding edges of upper frame I5 whereby an upwardly facing ledge I1 is provided.

The ends of frames I5, I6 adjacent endplates 2 are secured thereto, and the sidesY of the' frames adjacent the top I are securedltdthe latter: The upper inner corners of the end members I8 of frame I6 are rabbeted (Fig. 3) wherebytlie adjacent;A ends.

In operation when the ventilator is in the window, the desired amount of air can be admitted by'adjusting'tlieclosurezplatefZ, and' it is particularly pertinent to notethat tliev greater the amount of air that is admitted, the more such air is deected upwardly by plate 24, since said plate-wilL move to a position substantially parallel With top I when this plate is moved to fully open position.

Air. on thel sides of buildings tends to move directly upwardly along said sides, hence the outwardlyf projecting top I will deflect such air into the room andwill thereby tend to keep roomair ih` ci;duration, whereasi'fthe ventilator did not havei'tsopening directed downwardly, andv if it didlnot' project outwardly ofthe wall ofthe buildingno. such result would'be possible.

It; is olovi'c'iusL of"` course, that practically no moisturemay enter: the room through the ventilatorV duringga. rain, but" should the storm be one of' particular violence and` l'ackjof' direction, the fullline position of the closure' plate, 24' as; shown in.Fig. 2Will keep outtheY rain and will` at the same. time. provide. for ventilation.
